Abstract
Despite the scepticism raised by the German Monopoly Commission our analysis shows that the revised theory of contestable markets can be applied to the telecommunications market better than expected. The original contestable market theory implied three assumptions necessary to be satisfied to establish potential competition: Free market entry, market exit is possible without any costs, and the price adjustment lag exceeds the entry lag. Our analysis shows that if the incumbent reduces its prices slowly (high adjustment lag) and the market entry can be performed quickly (low entry lag), a new competitor will be able to earn back sunk costs. Therefore it is not necessary that all three conditions are satisfied for potential competition to exist. We applied the ‘revised’ contestable market theory to the German telecommunication market and have been able to clearly identify the value added stages in which regulation is required. Under the present conditions local loops - which can be determined as natural monopolies - are not contestable due to sunk costs, high entry lags expected and a probable short price adjustment lag. Local loops can be identified as monopolistic bottlenecks therefore. Regional and local connection networks should also be regulated because a high entry lag and a low price adjustment lag have to be expected as well as current competition does not exist today. The national connection network shows current competition between several network providers; hence regulation can be abolished in this field. Assumed that network access is regulated, services can be supplied by several competing firms.

The Role of Real Exchange Rates in the Central European Transformation

Abstract
The study eamines the interactions between real exchange rates, current accounts and capital account balances in Poland, Hungary and the Czech Republic. The empirical investigation leads to a strong endorsement of more flexible exchange rates in the present stage of the economic transformation process of the former socialist countries in Central and Eastern Europe. Exchange rate flexibility allows more independent monetary policies that focus on financing structural adjustments and institutional changes in transition economies. However, the integration process with the European Union and more remote considerations of possible accession to the European Monetary Union will require a gradual move to fixed exchange rates and to an exchangerate-based monetary policy.
